Located
in the northeast margin of the factory premises, this building was
destined to the mechanical manufacture of the pieces of cannons for
armament. With an area of 5,184 m2, it adopts a
compartmentalized plant in three adjoining naves, of identical light and
height, that are developed in elevation by means of two overlapping
levels that correspond to the plant and the basement.The overhead lighting is solved by a skylight oriented to the north that facilitates the protection of direct solar rays.Of note is the construction technology applied on the roof from the forged of armed ceramics

In
1856 the workshops were centralized, choosing the site occupied by the
monastery of La Vega, which was demolished - although some architectural
pieces were deposited in the Archaeological Museum of Asturias. Up
until that time the gilded masters had worked in their houses or in
small workshops, making the pieces that were then delivered to the
factory house located in the aforementioned palace; This
productive mechanism, of a trade union character, gave way, not being
able to satisfy the demand, to the creation of a great industrial
workshop. This
opens a modern factory run by Elorza, who in 1857 already owns armories
and steam-powered machinery and employs 700 gunsmiths and 250 auxiliary
workers. The Weapons Factory of Oviedo produces models like the carbines of the 57, rifles of the 59 and, from 1870, the Remingtons. In
1871 the demand caused by the Carlist War raises the number of workers
up to 1,000 workers, reaching the production of 30,000 rifles and
thirds. Before
the end of the nineteenth century, production was diversified with
models such as the Winchester rifle for the Civil Guard or the Mauser, a
statutory weapon of the army. During
the second half of the nineteenth century, a wooden warehouse, a
commissary and a cooperative, houses for managers, a library, a museum
and a basic school were added to the factory. Associated with the factory was created a School of Apprentices, in charge of forming skilled workers. The
origin of this center goes back to 1857, when it was concluded that the
children of the workers of the company should have the right to work
with their parents, who had to train them in the trade.
